This looks like a very nice pool. I don't have a lot of hash but I will give it a try and test out some of these cpu currencies with you.Do you have a promo banner that is more similar to the ones from other pools people show they are mining with in height I could put in my signature?

By matching Bitcoin and Namecoin block I'm thinking of an SHA-256 hash of [a list of Bitcoin transactions, some Bitcoin address information, and Namecoin data in a merkle tree] which happens to be a particularly low number (begins with quite a lot of 0s). It was my understanding that any hash small enough to generate a Bitcoin block would also be small enough to generate a Namecoin block and consequently I expected any merged mining Bitcoin block to have a corresponding Namecoin block (at least while Namecoin difficulty is less than Bitcoin difficulty).

If you have two or more examples of a share which generated a Bitcoin block but not a Namecoin block then I recommend looking into this and making sure that most BTC/NMC miners are working on headers with valid Bitcoin and Namecoin information most of the time. Caution: cgminer has had issues with merged mining because old versions doesn't like to change the block header when new work is pushed for Namecoin. The current version of PoolServerJ seems to be ok right now, even with cgminer, and you can see an example of it in action here: (BTC and NMC).

One suggestion would be that you use adapting units in the pool statistics.

So they show Mhash/s when the mining rate is below 1 Ghash/s and so forth. Could be useful particularly for the LTC and TBX pools yeah..

Also it would be nice to be able to see how many shares I have in the current round somewhere? edit: I found it eventually, though might want to show my individual stats in the pool seperate from the total pool stats somewhere
